8051-compatible FlashFlex51 microcontroller family enhanced

26 September 2001 DSP, Micros & Memory

Silicon Storage Technology's (SST), enhanced version of its SuperFlash-based FlashFlex51 family of 8 bit, 8051-compatible microcontrollers, the SST89C54 and SST89C58, incorporate 20 and 36 KB of integrated on-chip flash memory respectively.

Originally introduced in 1999, both products have been enhanced to include additional power saving features, improved in-application programming (IAP) capabilities and extended security modes with SoftLock advantages for robust software piracy prevention and inadvertent write protection. The feature set of these products was enhanced to provide added flexibility to the user and increased versatility of the on-chip flash memory. These enhancements make the FlashFlex51 family suitable microcontroller solutions for industrial applications such as vending machines, card readers and point-of-sale (POS) systems; PC peripherals such as scanners and printers; consumer devices; communication equipment; and medical instrumentation. Both products leverage SST's proprietary SuperFlash technology, which uses a small sector size for both code and data storage.
